I noticed some people coming to importprecision.com from here, so I decided to stop by and say hi. We do a direct bolt on vertical door conversion with no welding, cutting, drilling, or rolling of the fender. It opens both ways (OEM and vertical), and is a fully reversible installation because you use your stock bolts and the stock bolt pattern.
The way we do this is by designing the kit for each car specifically...that way you are getting a kit designed for your car, with the correct bolt pattern, shock pressure for the weight of your door, and fender clearance.
Because we make each kit specifically for each car, we are continuing to offer more cars models. We do not yet have a celica kit... but it does have a special place in my heart as my last car was a '92 celica GT. I loved that car.
There's lots of pics at importprecision.com... lemme know if you have any questions.
